We look at the division of 399668 by 35 
We want to figure out the number of times 399668 can be divided by 35.

Step 1:
35 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 35

Going ahead to step 2:
When dividing 39 by 35, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 4 after subtracting 35 from 39.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 35

Let's proceed to step 3:
35 goes into 49 1 times with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 14 after subtracting 35 from 49.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 35

Moving on to step 4:
35 can be fit into 146 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 114.0
Deduct 140 from 146 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 35

Moving on to step 5:
35 can be fit into 66 1 times, resulting in a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1141.0
Subtract 35 from 66 to get 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 35

Let's proceed to step 6:
35 can be fit into 318 9 times, resulting in a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 11419.0
If we take 315 away from 318, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 35, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 11419.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
35 can be fit into 300 8 times, resulting in a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 11419.08
If we subtract 280 from 300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
If we divide 200 by 35, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 11419.085
Subtract 175 from 200 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
If we divide 250 by 35, we get 7 and a remainder of 5.
The next digit of our result is 7. 
Result so far: 11419.0857
The remainder is 5 after subtracting 245 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
50 divided by 35 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 11419.08571
Deduct 35 from 50 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
If we divide 150 by 35, we get 4 and a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 11419.085714
Subtracting 140 from 150 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
If we divide 100 by 35, we get 2 and a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 11419.0857142
If we take 70 away from 100, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
If we divide 300 by 35, we get 8 and a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 11419.08571428
Deduct 280 from 300 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 11419.08571428, with a leftover of 2e-08.
